Set Bandwidth for App - webex/webex-ios-sdk GitHub Wiki

The application can specify the maximum bandwidth used by video, audio and screen sharing.

phone.audioMaxBandwidth = 64000 // 64kbps
phone.videoMaxBandwidth = 2000000 // 2Mbps for 1280x720 resolution

The unit of bandwidth is kbps.

The SDK uses the TIAS (Transport Independent Application Specific) maximum bandwidth modifier in the SDP to implement this functionality.
